GABRA1 and breast cancer: Importantly, GABRA1WT/WT expression rescued the number of target cells contacted by each GABRA1−/− BC (Figure 3H; GABRA1+/+ vs. GABRA1WT/WT; 61 ± 2% vs. 59 ± 4%; p > 0.05 and Figure 3H; GABRA1−/− vs. GABRA1WT/WT; 41 ± 3% vs. 59 ± 4%; p < 0.001) suggesting that biolistic transfection of GABRA1WT/WT under the PG67 promoter can drive the expression of enough protein to rescue GABRA1 deficits in single cells.
